A founder preparing to sell their service firm discovers during early conversations with prospective acquirers that a substantial share of the firm's actual client relationships and delivery expertise concentrate specifically in the founder personally and one senior colleague, and this concentration measurably depresses the offers being discussed relative to what the firm's revenue and profitability alone might otherwise suggest — a well-documented pattern called key person risk, reflecting genuine buyer concern about what happens to those concentrated relationships and expertise once an ownership transition actually occurs.
Why prospective acquirers specifically evaluate this concentration risk during due diligence
An acquirer purchasing a service firm is fundamentally purchasing its ongoing client relationships and its demonstrated ability to deliver value to those clients — if a substantial share of both depends specifically on one or two individuals whose continued presence through and after the transition isn't fully guaranteed, the acquirer faces genuine risk that a meaningful share of the business's actual value could depart alongside those specific individuals, whether through their own choice to leave or simply reduced engagement following a change in ownership.
How this risk concretely shows up in actual deal structure and pricing
Key person risk typically manifests as lower valuation multiples applied to the underlying revenue and profitability figures, earnout structures making a meaningful portion of the purchase price contingent on the key individuals actually remaining with the business for a specified retention period following the sale, or reduced upfront payment relative to what a comparable but less concentrated business would command — all reflecting the acquirer's rational pricing of the genuine risk that concentrated client relationships and expertise represent.
Why this risk often develops gradually and isn't necessarily obvious to the founder until a sale process actually begins
A founder deeply embedded in day-to-day client relationships and delivery work may not fully register how concentrated this dependency has actually become, since the firm continues functioning perfectly well under the founder's continued day-to-day presence — the concentration risk only becomes fully visible and consequential specifically when a sale process introduces the genuine prospect of that founder's reduced future involvement, at which point prospective buyers immediately and directly scrutinize exactly this dependency.
What deliberately distributing client relationships in advance of a sale actually accomplishes
Systematically introducing other senior team members into key client relationships well before any sale process begins, ensuring clients have genuine, established working relationships with people beyond just the founder, directly reduces the concentration risk a prospective acquirer would otherwise identify and price into any offer — this kind of deliberate relationship distribution takes real time to establish credibly, meaning it works best when begun years, not months, before an anticipated eventual sale.
What documenting institutional knowledge and building a genuine second layer of talent specifically addresses
Beyond client relationships specifically, institutional knowledge about delivery methodology, past client history, and internal processes that exists only in one or two people's heads represents its own distinct form of key person risk — documenting this knowledge into accessible, genuinely usable internal resources, and developing a genuine second layer of client-facing and delivery talent capable of operating independently of the founder's direct daily involvement, both directly and measurably reduce a service firm's overall key person risk profile.
What this means for founders planning an eventual sale of their service business
- Assess honestly how concentrated current client relationships and delivery expertise actually are in one or two specific individuals
- Begin deliberately distributing client relationships to other senior team members years, not months, before an anticipated sale process
- Document institutional knowledge into accessible internal resources rather than leaving it concentrated in individual memory
- Build a genuine second layer of client-facing and delivery talent capable of operating with real independence from the founder's direct daily involvement
Key person risk is a genuine, well-documented, and specifically priced consideration in service firm valuation — a founder who addresses this concentration deliberately and well in advance of an eventual sale process positions the business to command meaningfully better terms than one where this risk is only discovered once prospective buyers start actively asking about it.
